I am a linux novice with root access to an Ubunutn 10 VM which i connect to via putty. I want to connect to it via a GUI from windows xp so I have tried installing x11vnc on the machine and used realvnc from the xp client I have tried to install x11vnc on the machine as follows
This seems to load ok but removes the shell prompt. I presume the server has started and is listening on the ports so i used another putty window to reconnect to my machine and ran sockstat -l and xllvnc is listening on the 2 ports. I then downloaded realvnc windows client and entered the hostname to connect If i entered just the hostname or hostname:5900 i get a timeout error but if i enter hostname:5800 i get 'connection refused' error
By invoking x11vnc with the -gui tray option the TCL/TK GUI attempts to embed itself onto the system tray, but I encounter the error message "tail: cannot watch /tmp/x11vnc.tray.*", after the first settings dialog approved [clicked OK]. I believe that a package is still missing to be installed and this is not really a software bug. I use the XFCE version shipped along F15, and the GUI can be started but not as a docked-applet.
I have looked around and haven't had a lot of luck finding any information on this. I could be blind...but I'm not sure, haha.
I do a lot of remote support for my clients (I do PC repairs and training). I have recently starting suggesting to some of my basic users that they give Ubuntu a try. So far it has been very well received and they are loving it. The problem I am running into is that some of them use laptops in multiple places, and some use routers that are not easily configured. In each case it makes port forwarding a large pain in the behind to allow for remote access.
I have started using the X11vnc reverse connection and it has been working well, except for the fact that it is using high quality color depth (24bit I think?). I know when starting the connection from my end I can set the color depth, but is there any way to set the depth of a reverse connection?
Also, I understand that using just vnc over the Internet is not secure. I need to look into a decent guide to set up SSH tunneling for this. I don't suppose anyone knows of a good guide for 10.04 and 10.10?
I want to access my desktop from my laptop over the internet, after a while I found this [URL] so I followed the instructions "Access your PC over the internet" and "Logging in from another Ubuntu PC". Everything goes well until I try to run the shell script and get this: email@example.com's password:
I tried my luck with the passphrase associated with the rsa key, with the password of the laptopuser@laptop and with the password of the desktopuser@desktop but I keep getting Permission Denied (publickey, password).
Im trying to get vnc working over ssh between my windows pc and ubuntu server 11.04 natty over the internet. I have setup everything and got it all running automatically at boot on ubuntu. From within the local network i can use ssvnc and connect from a 2003 server to the ubuntu machine fine. Remotely I can connect and verify password over ssh but after that it tries to start tightvnc and fails. The issues seem to be on the windows side establishing the local connection to the tunnel or something I'm not a guru and I apologize if this is a windows issue but i think its likely that its a networking problem i need to forward or open a port somewhere but i cant find any easy to understand instructions so far in getting this running
This is the output in the putty terminal after running ssvnc slightly modified ive taken out my real username and server address I use user@server:0 as the arguments for ssvnc
Code: Looking up host "server" Connecting to server-ip port 22 Server version: SSH-2.0-OpenSSH_5.8p1 Debian-1ubuntu3 We claim version: SSH-2.0-PuTTY_Release_0.60 Using SSH protocol version 2
Does anyone have any ideas why the connection fails at the point of using the tunnel? is it a problem on the ubuntu or windows side?
I am working with Ubuntu for the first time since school and it was an intro class. I am trying to setup a file server for part of a school project. I installed x11vnc and am trying to set the password. However everywhere I look says the file would be located at ~/.vnc/passwd. However when I ls from the home directory .vnc does not exist. When I type out vncpasswd ~/.vnc/passwd I get returned a message The program 'vncpasswd' can be found in the following packages:
* tightvncserver * vnc4server
how I can get this setup? Am I using old information that is no longer accurate or am i messing this up somewhere?
I'm trying to set up x11vncto run at the login screen. This is so that the computer can be powered up remotely using Wake-On-LAN and then controlled remotely. I'm following this tuorial: [URL]I'm having some trouble whit the section about adding to the GDM config files. The tutorial asks me to add
Code: #to get remote vnc to not die after login KillInitClients=false
I'm creating a new thread based on this post by batagy:
So I have running x11vnc as service without any problem (running on Solaris 10 and SLES10 too). I'm using the x11vnc's inbuilt "user chooser" screen (that little black screen), these command line options:
x11vnc -inetd -unixpw -users unixpw= -display WAIT:cmd=FINDCREATEDISPLAY-Xvnc.xdmcp -env X11VNC_CREATE_GEOM=1248x900 (plus a couple of other options that are not interesting here)
My question is related to the wanted VNC screen size. By default, I set the defauls screen size to 1248x900, as can be seen above.
Currently , when a user want to personalize his/her screen size to be started, he can do it this way: when the small black authentication window is appearing first, after his username, he's entering a colon, then specify the wanted resolution in this format: geom=1600x1200.
My question: is it possible somehow to set automatically the preferred screen size, without entering this ":geom=1600x1200" string in the authentication window? I mean to set it per user, without modifying the service options. I mean, for example setting the X11VNC_CREATE_GEOM or FD_GEOM variables in the user's home ".profile" for example?
I upgraded to Lucid yesterday. All of them solved, except this one: when I connect to my kubuntu PC from a Windows PC and launch x11vnc on the remote and TightVNC on the local, it keeps repainting the window making it unusable. Nothing gets printed to the log when the repaintings occur. Using -noxdamage or -nowf doesn't change a thing. -ncache doesn't work (I get an "ERROR: No active KDE sessions!").
I'm using Ubuntu 10.04, and I'm trying to VNC into my Ubuntu box from my MBP. I can connect just fine, however, I am unable to register any mouse clicks or keyboard input on the resulting desktop. I'm launching it as follows: x11vnc -nomodtweak -scale 9/10 I can log in using my Windows box and UltraVNC and use input with no problem.
At the moment I'm running Putty on a windows box at work to SSH in and tunnel port 5900, then I execute
Code: x11vnc -xkb -ncache 10 -safer -localhost -nopw -once -display :0 from the shell.
I run ssvnc and tell it to connect to localhost, and we're good for remote desktop.
The next step is to push my luck and see if I can get streaming audio as well.
ssvnc is supposed to automate many of the required processes, making the use of a standalone ssh client like Putty redundant - it bundles a similar program, passing commands through ssh from its GUI
Under options/advanced it has a facility to 'Enable ESD/ARTSD' audio tunnelling and it bundles a windows-executable (using cygwin library) version of ESD, so it just needs some configuration.
When you click that option there's a documentation pane that says you can put
esddsp -s localhost:16001 gnome-session
in your ~/.xsession startup file but since I use my Lucid box for local sound as well I'm not sure that's ideal as I want to use JACK, etc. and it looks like this command would route all audio to network, all the time.
ssvnc suggests using "x11vnc -create" mode to start it up in a virtual X session through Xvfb but it doesn't really go into any more detail as to how you do this.
I've installed Xvfb through synaptic, and that's as far as I've gotten.
Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?
I later ran sudo apt-get install ubuntu-desktop to see if that would help.
Code: #cat /etc/issue Ubuntu 10.04.1 LTS l Code: #sudo startx Fatal server error: xf860OpenConsole: Cannot open /dev/tty0 (No such file or directory) I assume this is because it probably doesn't have a video card. [Code]...
I have x11vnc server set up on my desktop PC. I can boot the computer and connect at the login screen if I want to. I can login to my computer as usual. But after about 1 minute of logging in, the computer logs off as if pressing Ctrl+Alt+Backspace and returns me to the login screen. This cycle repeats when I login and I have to kill the x11vnc process or remove the command from /etc/gdm/Init/Default.Have tried so many things now but the end result is the same. I have Ubuntu 10.10 fully updated and x11vnc 9.10-1 from the default repos. I am using the following command in the /etc/gdm/Init/Default file:
I don't think it matters now whether I add KillInitClients=false into /etc/gdm/gdm.conf-custom or /etc/gdm/gdm.conf because of the x11vnc version I have. The manual says its not really needed. But I have tried this too with no better luck.The computer will still log me out after about a minute of logging in. It can be between 1 min to 1.5 mins.Running out of ideas and have tried the -noxfixes and -reopen commands.
Why does x11vnc crash out (or it may be gdm or x server?) after about a minute of logging in? If I am currently viewing my desktop through VNC viewer on another computer, it will still crash out after 1 min of log in, and lose the connection. I can reconnect through VNC again but I have to log back in to the remote computer and it will just log out after another minute.At last, in 2 days I have finally solved it. As simple as creating my own version. The x11vnc 9.10-1 version my default Ubuntu 10.10 repos is buggy. Here's my fix (I used this site):
1. Downloaded latest x11vnc dev build from above site (x11vnc-0.9.13-dev.tar.gz at time of posting) 2. Extract it 3. Open Terminal > sudo -s > enter admin password 4. cd LocationOfExtracted folder
Before we use CentOS 4 and all work fine. We start x11vnc by ssh like root. And after this connect by client login in X screen. In CentOS 5 this way don't work. For connect we must login by local from keyboard, start x11vnc ssh by logined local user, and after this we may work, but can't change users.
How come on x11vnc, with Fedora 12 PPC/x86/x64, my screen sizes can't be greater than 800 x 600, and they don't update when I change them in Displays. On my Ubuntu installations the x11vnc screen sizes update and can be basically any size selectable in Monitors.
Sorry if this is in the wrong group but its a bit of an odd one but I think comes under Server Support.. I've set up both x11vnc and freenx in an attempt to eliminate either as a cause for this issue. The problem is that when I log in with either, I can get into the desktop and run things from the menus but when I make the System menu active - the session hangs and you have to killall for the freenx or vnc processes.
I was wondering if anyone might be able to help me investigate this and hopefully fix it as I'm not sure where to look given that both types of remote connection seem to have the same issue.
I've been learning linux for a while now with half an eye on making a career out of it in future. One sizeable gap in my knowledge at the moment is networking. Is it feasible/desirable to set up a network of virtual machines to use as an environment to learn networking? My budget is non-existent so I was hoping to be able to get a basic understanding of the principles from installing a few desktops, a virtual gateway etc on VMware workstation on my laptop, and doing a lot of reading online.
Is this feasible, or will I just end up learning about virtual networks instead of real ones? Also how much power would be required, because my 3GB RAM lappy has just gone bang and all I have now is a (new) 1GB RAM lappy.
I have multiple devices in my garage that need internet connectivity. I have my main Netgear router inside the house. I have a computer running Ubuntu in the garage with dual NICs.
Here's a map of how I have it setup now: [URL] Here's my /etc/network/interfaces: Code: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.60 netmask 255.255.255.0 gateway 192.168.1.1
I was trying to keep everything on the same subnet. Eth0 is the external NIC, connected to the router in the house. eth1 is the internet NIC, which would go out to the devices in the garage. Now, I know it would be easiest to just connect a switch up and run all the devices in the garage off that switch. But the switch I have is a 10/100, and my network in the house is gigabit, and I want the PC in the garage to have gigabit access... which is why I'm doing this dual NIC setup and using the PC as a router, then the other devices in the garage will be 10/100.
In addition, I used the shell script as described in this article: [URL] to setup iptables. I also uncommented the net.ipv4.ip_forward=1 line in /etc/sysctl.conf. What am I doing wrong here? None of the devices in the garage that I connect up to the Ubuntu PC are getting connectivity. None are getting a DHCP lease from the main router in the house. The Ubuntu PC itself has internet access just fine though.
I just bought a old xeon server and am installing ubuntu 10.10 with ltsp, i have also bought 3 thin clients to add to it, what kind of hub or switch do i need to use with it? also is it straight through or crossover cat5 cables that i need? is there any good sites that i should look at for setting this all up, my end goal is to have educational stuff on them for my kids with internet enabled only at certain times, and have movies available from the server for them to watch.
I recently bought the D-Link DIR-655 and DWA-140 wireless setup just before converting completely to Linux from windows. I'm sure there are issues with the ralink rt2870 chipset. I did get this to work after a few days of trying various things, but I could not get Wireless N to work, it only operates in G mode. This seems to have something to do with needing to use AES for N-mode. My wireless setup will only work with Ubuntu if I have TKIP set. This of course requires my entire network to work at G speeds. Consequently I am returning my D-Link setup tomorrow, and am looking for the community opinion on what Router/adapter setup is truly out-of-the-box compatible with Ubuntu 10.04. This Router will need to be compatible with other windows based computers on the network running the DWA-140 USB adapters. (I have no PCI slots available).
